ion-select

Selects are form controls to select an option, or options, from a set of options, similar to a native <select> element. When a user taps the select, a dialog appears with all of the options in a large, easy to select list.

A select should be used with child <ion-select-option> elements. If the child option is not given a value attribute then its text will be used as the value.

If value is set on the <ion-select>, the selected option will be chosen based on that value. Otherwise, the selected attribute can be used on the <ion-select-option>.

Interfaces

By default, select uses the AlertController API to open up the overlay of options in an alert. The interface can be changed to use the ActionSheetController API or PopoverController API by passing action-sheet or popover, respectively, to the interface property. Read on to the other sections for the limitations of the different interfaces.

Single Selection

By default, the select allows the user to select only one option. The alert interface presents users with a radio button styled list of options. The action sheet interface can only be used with a single value select. The select component's value receives the value of the selected option's value.

Multiple Selection

By adding the multiple attribute to select, users are able to select multiple options. When multiple options can be selected, the alert overlay presents users with a checkbox styled list of options. The select component's value receives an array of all of the selected option values.

Note: the action-sheet and popover interfaces will not work with multiple selection.

Object Value References

When using objects for select values, it is possible for the identities of these objects to change if they are coming from a server or database, while the selected value's identity remains the same. For example, this can occur when an existing record with the desired object value is loaded into the select, but the newly retrieved select options now have different identities. This will result in the select appearing to have no value at all, even though the original selection in still intact.

By default, the select uses object equality (===) to determine if an option is selected. This can be overridden by providing a property name or a function to the compareWith property.

Select Buttons

The alert supports two buttons: Cancel and OK. Each button's text can be customized using the cancelText and okText properties.

The action-sheet and popover interfaces do not have an OK button, clicking on any of the options will automatically close the overlay and select that value. The popover interface does not have a Cancel button, clicking on the backdrop will close the overlay.

Interface Options

Since select uses the alert, action sheet and popover interfaces, options can be passed to these components through the interfaceOptions property. This can be used to pass a custom header, subheader, css class, and more.

See the AlertController API docs, ActionSheetController API docs, and PopoverController API docs for the properties that each interface accepts.

Note: interfaceOptions will not override inputs or buttons with the alert interface.
