Prevent AP element overlaps

Because table cells cannot overlap, Dreamweaver cannot create a table from overlapping AP elements. If you plan to convert the AP elements in a document to tables, use the Prevent Overlap option to constrain AP element movement and positioning so that AP elements don’t overlap.

When this option is on, an AP element can’t be created in front of, moved or resized over, or nested within an existing AP element. If you activate this option after creating overlapping AP elements, drag each overlapping AP element to move it away from other AP elements. Dreamweaver does not automatically fix existing overlapping AP elements in the page when you enable Prevent AP element Overlaps.

When this option and snapping are enabled, an AP element won’t snap to the grid if it would cause two AP elements to overlap. Instead, it will snap to the edge of the closest AP element.

Note: Certain actions allow you to overlap AP elements even when the Prevent Overlaps option is enabled. If you insert an AP element using the Insert menu, enter numbers in the Property inspector, or reposition AP elements by editing the HTML source code, you can cause AP elements to overlap or nest while this option is enabled. If overlaps happen, drag overlapping AP elements in the Design view to separate them.
  • In the AP Elements panel (Window > AP Elements), select the Prevent Overlaps option.
  • In the Document window, select Modify > Arrange > Prevent AP Element Overlaps.
