In Flexitive, most customization options for elements are in the Customize panel. The customize panel is on the left-hand side of the editor, and can be opened using the Hammer & Wrench icon.
In the Customize panel, you can make changes to an element, such as changing visibility, opacity or position. Elements such as Shapes, YouTube Videos and MP4 Videos will have additional customization options available to edit that particular type of element.
To make a change to an element using the Customize panel, select the element on the canvas or in the Layers Panel and open the Customize panel by tapping the Hammer & Wrench icon on the left-hand side of the editor. After tapping the Hammer & Wrench icon, you will have access to all of the customization options for the element.
If you ever have a question about what an option in the customize panel does, you can tap the "i" icon to be forwarded to open a related support article in a new tab.
