Dropdown

A dropdown

A dropdown can be formatted so that its menu is pointing

Bottom pointing dropdown menus have sub-menus open upwards

A dropdown menu can appear to be floating below an element.

Save

A simple dropdown can open without Javascript

An active dropdown has its menu open

An active state will only automatically open a ui simple dropdown. To activate a normal dropdown use $('.ui.dropdown').dropdown('show');

A disabled dropdown menu or item does not allow user interaction

Using the clearable setting will let users remove their selection from a dropdown.

Show me classes currently available.

$('.clearable.example .ui.selection.dropdown') .dropdown({ clearable: true }) ; $('.clearable.example .ui.inline.dropdown') .dropdown({ clearable: true, placeholder: 'any' }) ;

Using maxSelections lets you force a maximum number of selections. You can also use form validation rules to specify minimum and maximum validation settings for multi-selects inside forms.

$('.max.example .ui.normal.dropdown') .dropdown({ maxSelections: 3 }) ; $('.max.example .ui.special.dropdown') .dropdown({ useLabels: false, maxSelections: 3 }) ;

Using allowAdditions: true gives users the ability to add their own options. This can work with either single or multiple search select dropdowns

Although all dropdowns support select initialization, custom choices will not be saved on page refresh unless you use a hidden input. This is because option created dynamically are not preserved on page refresh.

$('.tag.example .ui.dropdown') .dropdown({ allowAdditions: true }) ;

Sometimes multiselect include options which are long and would appear awkwardly as labels. Setting useLabels: false will display a selected count, and allow reselection directly from the menu.

You can customize any of the messages displayed by adjusting templates in settings.message

$('.no.label.example .ui.dropdown') .dropdown({ useLabels: false }) ;

A dropdown menu will automatically change which direction it opens if it can't fit on screen. If you need a dropdown to open in a specific direction you can specify it when initializing a dropdown.

$('.upward.example .dropdown') .dropdown({ direction: 'upward' }) ;

Search selection dropdowns can specify API settings for retrieving values remotely, this can use either a named API action or url.

Using API can allow users to select choices from large datasets that would be too large to include directly in page markups.

If your backend is not designed to return the correct markup you can use API's onResponse callback to adjust the format of an API response after it is received from the server.

Requests for the same API endpoints will automatically cached locally, to avoid server roundtrips. You can disable this by adjusting the cache API setting.

When a user refreshes the page, selection labels are automatically recreated by using sessionStorage to store the corresponding names for selected values. You can disable this feature by setting saveRemoteData: false

$('.remote.filter.example .ui.dropdown') .dropdown({ apiSettings: { // this url parses query server side and returns filtered results url: '//api.semantic-ui.com/tags/{query}' }, }) ;

// Expected server response { "success": true, "results": [ { // name displayed in dropdown "name" : "Choice 1", // selected value "value" : "value1", // name displayed after selection (optional) "text" : "Choice 1" // whether field should be displayed as disabled (optional) "disabled" : false }, { "name" : "Choice 2", "value" : "value2", "text" : "Choice 2" }, { "name" : "Choice 3", "value" : "value3", "text" : "Choice 3" }, { "name" : "Choice 4", "value" : "value4", "text" : "Choice 4" }, { "name" : "Choice 5", "value" : "value5", "text" : "Choice 5" } ] }

When possible choicesets are large, ideally API results should only return values matching the passed query term to reduce transmissions over the wire. However if there are only a few hundred or less choices, you may consider returning the full set of results from an API endpoint and filtering them against the query clientside using the setting filterRemoteData: true.

$('.remote.choices.example .ui.dropdown') .dropdown({ apiSettings: { // this url just returns a list of tags (with API response expected above) url: '//api.semantic-ui.com/tags/' }, filterRemoteData: true }) ;

A dropdown can specify a different transition.

$('.dropdown') .dropdown({ // you can use any ui transition transition: 'drop' }) ;

Toggle

Using a multi-level menu with allowCategorySelection: true will allow items with sub-menus to be selected.

$('.category.example .ui.dropdown') .dropdown({ allowCategorySelection: true }) ;

A button can be formatted with a dropdown.

Using the combo action will change the preceding element to the selected value.

$('.combo.dropdown') .dropdown({ action: 'combo' }) ;

Save

Dropdowns support different default actions that can occur when an item is selected. For example, you can set your dropdown not to change its text, or select a value from its menu.

$('.link.example .dropdown') .dropdown({ action: 'hide' }) ;

A menu element can contain a dropdown

Initializing a dropdown with pre-existing HTML allows for greater performance than initializing a dropdown directly on a select element.

Any select element initialized as dropdown will also be hidden until Javascript can create HTML, this is to avoid the flash of unstyled content, and the change in element height adjusting page flow.

$('.ui.dropdown') .dropdown() ;

You can specify a list of values in the settings object to avoid having to stub the html yourself.

Adding selected: true to an item will have that item selected by default.

You can also use the placeholder setting to specify placeholder text before an option is selected.

$('.ui.dropdown') .dropdown({ values: [ { name: 'Male', value: 'male' }, { name : 'Female', value : 'female', selected : true } ] }) ;

For convenience, select elements can automatically be converted to selection dropdown. A select options with blank string values will be converted to prompt text.

$('#select') .dropdown() ;

As a third option, you can include a wrapper around your select so that it will appear correctly on page load, but will then populate the hidden menu when Javascript fires. In this case, the select element does not receive the ui dropdown class.

$('#hybrid select') .dropdown({ on: 'hover' }) ;

Using a search selection dropdown will allow you users to search more easily through large lists. This can also be converted directly from a form select element.

$('#search-select') .dropdown() ;

You can allow multiple selections by the multiple property on a select element, or by including the class multiple on a dropdown.

When pre-existing HTML with a hidden input is used, values will be passed through a single value separated by a delimiter. The default is "," but this can be changed by adjusting the delimiter setting.

$('#multi-select') .dropdown() ;

Dropdowns have multiple built-in actions that can occur on item selection. You can specify a built-in action by passing its name to settings.action or pass a custom function that performs an action.

Action	Description
activate (Default)	Selects current item, adjusts dropdown value and changes dropdown text
combo	Same as activate, but updates previous elements text instead of self
select	Selects current item from menu and stores value, but does not change dropdown text
hide	Hides the dropdown menu and stores value, but does not change text
function(text, value){}	Custom action
nothing	Does nothing

To specify a different built in action, simply specify the name.

$('.dropdown') .dropdown({ action: 'combo' }) ;

To trigger only your custom action and no default action, specify your own function for settings.action.

$('.dropdown') .dropdown({ action: function(text, value) { // nothing built in occurs } }) ;

If you want to have both a built in action occur, and your own custom action use onChange in combination with action

$('.dropdown') .dropdown({ action: 'hide', onChange: function(value, text, $selectedItem) { // custom action } }) ;

All the following behaviors can be called using the syntax:

$('.your.element') .dropdown('behavior name', argumentOne, argumentTwo) ;
