Users can either choose from the existing items by clicking the drop-down arrow or enter their own value as text by clicking the component. error can occur if one of the deleted values was the selected list item. In a file named imageApp.m, write a function that implements the app: Create an editable drop-down component and an image component in the grid layout manager. The list value is the list of items to present in the dialog box. Run the plotOptions function. When Editable is set to 'on', you can function DropDown1ValueChanged (app, event) Here you go: classdef app1 < matlab.apps.AppBase. arrow buttons to the right of the value. To link the value of a control to a workspace variable, set the default value to the outer bottom edge of the drop-down component, Distance between the right and left outer edges of the drop-down By default, Value is the selected item. variable from the drop-down list.
