Does it work with classic themes?
No. Panels are template parts, which need a block theme. Classic themes can use a classic menu plugin.
Where do I find my panels?
Appearance → Mega Menus lists them all with an Edit button. They are also in Appearance → Editor → Patterns → Mega Menu, and the block settings link to the chosen panel.
Where is Appearance → Menus?
Block themes have no Menus screen; menus are made with the Navigation block in Appearance → Editor. Mega Menu items go inside that Navigation block.
The panel opens too high, on top of my header
The panel opens right under the menu item. If your header is taller, use Space above in the Style tab to move it down.
What happens on phones?
When the Navigation block turns into a phone menu, the panel opens under its item inside that menu. With a link on the item you can choose Go to link instead, then the item is a normal link on phones.
I switched themes and my panels are gone
Template parts belong to a theme. Switch back to see them, or copy the blocks into new panels in the new theme.
