how to select with the mouse multi fields by the layout mode in file maker

You can drag a rectangle across multiple objects on a layout. Each object that is wholly contained in the selection rectangle will be selected. If necessary, you can shift-click on any unselected objects to add them to the selection, or shift-click on any of the already-selected objects to deselect them.

You can also use Command-A (on Mac) or Ctrl-A (on Windows) to select all the objects on the layout.

even when drag a rectangle across multiple objects on a layout it's not been selected i don't know why?

thanks alot

Actually, you can select objects without completely enclosing them by holding down the Command (Mac) or Control (Win) key while clicking and dragging the selection marquee. Any object that the marquee touches will be selected even if you don't surround it entirely.

In addition, a very useful keyboard shortcut for selected all objects on a layout of a similar type - all lines, all fields, all text all buttons - is to click on one object, and then type Control-Alt-A (Win) or Command-Alt-A. The "Alt Select All" function then selects all objects on the layout of the same type. Very useful if you want to change the font or font size for all fields or field labels on a layout. (Note that this does not apply to grouped objects).
