Adding a drop-down button to a layout negates all client-side tabbing on that layout
How to replicate
Open & host any one of the starter solutions in FileMaker Pro Advanced 14 on FileMaker Server. Open the solution and navigate to the Startup page (this page should be blank). Add a series of fields to the layout and navigate to the layout in Web Direct. Tabbing through the fields is speedy.
Now add a dropdown button to the layout and try tabbing through the fields.
Workaround (if any)
Do not use dropdown buttons in layouts in Web Direct that require the user to tab through fields
