Select2 hide options

Select2 is licensed under MIT. A search box is added to the top of the dropdown automatically for select boxes where only a single option can be selected. The behavior and appearance of the search box can be easily customized with Select2. When users filter down the results by entering search terms into the search box, Select2 uses an internal "matcher" to match search terms to results. You may customize the way that Select2 matches search terms by specifying a callback for the matcher configuration option.

Select2 will pass each option as represented by its internal representation into this callback to determine if it should be displayed:. When a remote data set is used, Select2 expects that the returned results have already been filtered on the server side.

Only first-level objects will be passed in to the matcher callback. If you are working with nested data, you must iterate through the children array and match them individually. This allows for more advanced matching when working with nested objects, allowing you to handle them however you want. A compatibility module exists for using v3-style matcher callbacks.

Sometimes when working with large data sets, it is more efficient to start filtering the results only when the search term is a certain length. This is very common when working with remote data sets, as it allows for only significant search terms to be used.

In some cases, search terms need to be limited to a certain range. Select2 allows you to limit the length of the search term such that it does not exceed a certain length.

You may limit the maximum length of search terms by using the maximumInputLength option:. The minimumResultsForSearch option determines the minimum number of results required in the initial population of the dropdown to display the search box.

This option is useful for cases where local data is used with a small result set, and the search box would simply be a waste of screen real estate. Set this value to -1 to permanently hide the search box. For single selects, Select2 allows you to hide the search box using the minimumResultsForSearch configuration option. In this example, we use the value Infinity to tell Select2 to never display the search box.

For multi-select boxes, there is no distinct search control.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Have a question about this project?

In a multi select I would like to be able to hide the already selected options from the dropdown. I tried to use display: none; but when I navigate through the options with the arrow keys the hidden options are still highlighted. I'm also trying to hide the new tag option when it is a duplicate of an already available option, but since it is the first element in the dropdown if the user presses enter this will be the selected one even if not visible If not possible to disable is there an event being triggered on highlight?

I have a use case for this too. I was attempting to stylize the "disabled" options so it was visually obvious which elements were flagged as disabled without having to mouseover any scrutinize the cursors hover state or add text to the end of the displayed value.

The Select2 demo for disabled options requires manually adding text " disabled " to the end of the label to indicate the option is disabled. After a little research, I've found that I could apply styles to disabled options by using the following CSS aria selector. NOTE: I'm not sure if this will work in all browsers.

I tested it using Firefox Dev Hello I came across this same solution earlier today, however there is an issue with navigation. When using arrow keys to navigate, the hidden options still "take up" an entry. So perhaps there is an improvement that could be made in this regard such that arrow navigation could skip over hidden options? There is a good reason that you wouldn't want to remove a selected item from the list completely. See Kevin's explanation in :.

This is to command for toggling a result, so it will select or unselect the highlighted result depending on what state it was previously in. Screen readers should read out the state of the option whether it is selected or not as they move through the results list, which is usually important.

Without an alternate way to unselect arbitrary options using the keyboard, the UX problems caused by that far outweigh the UX annoyances that you currently have by showing the selected results. What is the benefit of screen readers using select2 at all?

Please note, I'm not trying to talk negative about select2, but I genuinely don't know the answer. You could also simplify the code to not use any aria attributes.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Every single item is wrapped in li. I would really appreciate if there is also some other class added to currently selected item in this ul. That way I can target it by CSS and hide that item. This change would only affect the single select.

The multi select already uses a css class for selected items called select2-selected. If a CSS class were to be added to the currently selected element, it should be added in both single and multiple select modes for consistency. The elements of a multiple select cannot be selected multiple times, once an item is selected it gets removed from the results filtering is done using the select2-selected class.

In the case of the single select, the selected element still shows up highlighted in the results. What srigi mentions is beeing able to hide this element from the results the same way it happens for multi select.

Maybe what we really should do is allow to user to hide the currently selected element from the results in a single select. For instance, if you have already selected Oregon then it doesn't show up in the result list as in the following example:.

This way we would use the same CSS class for both single and multi select select2-selected. This option could be a boolean configuration value called hideSelectionInSingle false by default. Later it could be made more generic once the multi select allows duplicated items. Closed by The pull request was reverted because of issues discovered in I'm open to a revised implementation, though I'm not sure how it would be possible to get past the val issue.

Could you also revert the documentation for it? Select2's internal data structure filters out duplicate, this could be changed but would require lots of changes. The way I ended up doing it is as follow: I added a property to allow the same item to be selected multiple times only for multiple select.

When the user submits the page, I keep track of the seleted elements inside a hidden input:. Commenting the code that prevents the same item to be selected multiple times is an option example provided by kanthu This issue was closed because of work in but that pull request was reverted, so the problem remains.Select2 is licensed under MIT.

See High value of minimumResultsForSearch only hides searchbox in opened select. But if we type some letter while select is closed and focused - search will pop up, no matter how high is minimumResultsForSearch and how many actual options in select we have. So we need more convinient way to disable searching As stated inhiding the input alone really doesnt solve the problems you may encounter.

Would be helpful to mention this in the docs. Too maintain consistent styling I use select2 for all my selects. A select with two or three options doesn't need a search field. I did a little debugging and it seems like the second time it opens the dropdown minimumResultsForSearch would be set to 0 automagically for some reason. For current versionyou should set to a enough positive number, liketo disable search box.

None of this seems to work with the latest version 4. I have a multiple select box and I'm still getting the search icon might be a bug. I tried different settings with minimumResultsForSearch. Your right one of the CSS stylesheets was still loading. Thanks for the help. I edited the select2. Skip to content.

To enable tagging, set the tags option to true :.

Note that when tagging is enabled the user can select from the pre-existing options or create a new option by picking the first choice, which is what the user has typed into the search box so far. Tagging can also be used in multi-value select boxes. Try entering a value that isn't listed in the dropdown - you'll be able to add it as a new option!
