In CTRwow we have Tooltips for the Widgets available in the Page Builder>Elements.
What is a Tooltip?
A Tooltip is a brief, informative message that appears when a user interacts with an element in a graphical user interface. They are initiated when the mouse-hover on one of the elements.
In CTRwow specifically, on the Elements section of the Page Builder, Tooltips are attached to the drag-and-drop Widgets blocks and are triggered by the mouse hovering over the block, so a question mark icon will pop up in the top right corner of it.
Here is an example of the Tooltip on the Facebook Comment Widget block.
When the user clicks on that question mark icon, a small tab will pop up on the side of the block, and it will display a little explanation about the paired Widget.
