Dynamic Div
A dynamic div is a blank, editable content region — the basic building block you drop text, images, or other content into via in-line editing.

Step 1: While editing a page, find the vertical icon rail on the left edge of the page canvas. Dynamic Div is the top icon (a +).
Step 2: Drag it onto an empty region of the canvas. Unlike every other component in the rail, Dynamic Div has no picker — it inserts directly and is immediately ready for content.
