By applying the triggers you can give action to the button like playing a video or showing layer content, etc. All these types of actions can be controlled by giving triggers to the buttons.
The next type of making buttons work is, converting the buttons to freeform where the user can interact with the buttons like selecting the options in multiple-choice or multiple response.
Another way to make the buttons work is, creating a button set. Add three or more buttons in a slide, then select all the buttons and right-click on any of the buttons. Select the option button set and add it to the new set. In the preview you can see when we select one button the other buttons are in disable mode.
Note: You can add checkboxes and radio buttons under the input section and the rest of the functionality is the same as adding buttons.
