ComboBoxComponent

Enables or disables the adaptive mode. By default the adaptive rendering is disabled.

Specifies whether the ComboBox allows user-defined values that are not present in the dataset (more information and examples). Defaults to false.

The feature is not available when using adaptive mode.

If set to true, renders a button on hovering over the component. Clicking this button resets the value of the component to undefined and triggers the change event.

Sets the data of the ComboBox.

The data has to be provided in an array-like list.

Sets the disabled state of the component. To learn how to disable the component in reactive forms, refer to the articles on ComboBox Forms Support and MultiColumnComboBox Forms Support.

Sets the fillMode of the component.

The possible values are:

• flat
• solid (default)
• outline
• none

Enables the filtering functionality. If set to true, the component emits the filterChange event.

Sets the HTML attributes of the inner focusable input element. Attributes which are essential for certain component functionalities cannot be changed.

Defines a Boolean function that is executed for each data item in the component (see examples). Determines whether the item will be disabled.

Sets the height of the options list in the popup. By default, listHeight is 200px.

The listHeight property affects only the list of options and not the whole popup container. To set the height of the popup container, use popupSettings.height.

When using adaptiveMode and the screen size is small or medium the listHeight property is set to null.

Sets and gets the loading state of the ComboBox.

The hint that is displayed when the component is empty.

Configures the popup of the ComboBox.

The available options are:

• animate: Boolean—Controls the popup animation. By default, the open and close animations are enabled.
• width: Number | String—Sets the width of the popup container. By default, the width of the host element is used. If set to auto, the component automatically adjusts the width of the popup and no item labels are wrapped. The auto mode is not supported when virtual scrolling is enabled.
• height: Number—Sets the height of the popup container.
• popupClass: String—Specifies a list of CSS classes that are used to style the popup.
• appendTo: "root" | "component" | ViewContainerRef—Specifies the component to which the popup will be appended.

Sets the read-only state of the component.

Sets the border radius of the component.

The possible values are:

• small
• medium (default)
• large
• full
• none

Shows or hides the current group sticky header when using grouped data. By default the sticky header is displayed (see example).

Sets the size of the component.

The possible values are:

• small
• medium (default)
• large
• none

Sets the subtitle of the ActionSheet that is rendered instead of the Popup when using small screen devices. By default the ActionSheet subtitle uses the text provided for the placeholder of the AutoComplete.

Enables the auto-completion of the text based on the first data item.

Specifies the tabindex of the component.

Sets the data item field that represents the item text. If the data contains only primitive values, do not define it.

The textField property can be set to point to a nested property value - e.g. category.name.

Sets the title of the ActionSheet that is rendered instead of the Popup when using small screen devices. By default the ActionSheet title uses the text provided for the label of the AutoComplete.

Sets the value of the ComboBox. It can either be of the primitive (string, numbers) or of the complex (objects) type. To define the type, use the valuePrimitive option.

All selected values which are not present in the dataset are considered custom values. When the Enter key is pressed or the component loses focus, custom values get dismissed unless allowCustom is set to true.

Sets the data item field that represents the item value. If the data contains only primitive values, do not define it.

The valueField property can be set to point to a nested property value - e.g. category.id.

A user-defined callback which returns normalized custom values. Typically used when the data items are different from type string.
