jQWidgets jqxDropDownList insertAt() Method

Last Updated : 11 Sep, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxDropDownList widget is a jQuery drop-down list that contains a list of selectable items displayed in the drop-down list.

The insertAt() method is used to insert a new item to the jqxDropDownList. It returns true if the new item is inserted or false if insertion fails. It accepts two parameters, the first one is an item of String/Object type and the second is an index of Number type.

The following fields can be used for the item.

label: It specifies the label of the item.
value: It specifies the value of the item.
disabled: It specifies whether the item is enabled/disabled.
checked: It specifies whether the item is checked/unchecked.
hasThreeStates: It specifies that the checkbox item supports three states.
html: It specifies the display item in HTML. It can be used instead of a label.
index: It specifies the item index number.
group: It specifies the item’s group.

Syntax:

$("Selector").jqxDropDownList('insertAt', item, index);
