Value range

single

Only one item can be selected and active at a time.

multiple

Several items can be selected and active, whereby items can be selected and deselected one by one with a mouse click.

Compatible to .multisel = true.

extended

Several items can be selected and active, whereby an existing selection can be expanded and reduced by mouse clicks in combination with the Ctrl and Shift keys. Multiple items can be selected and deselected at once using the Shift key.

In detail, the behavior is as follows:

User Operation	Selection
Click	delete current selection, activate current element
Shift + Click	maintain current selection, activate area from last Click without Shift to current element
Ctrl + Click	maintain current selection, toggle activation of current element
Shift + Shift + Click	maintain current selection, area from last Click without Shift up to current element gets activation of the first one

The interaction of .selstyle with attribute .selection[enum], which is used to select a selection type in the tablefield, is described in the following table:

Selection Type	Current Element
sel_single	one field
sel_header	one field of header
sel_row	one row
sel_column	one column

Note for .selstyle single and extended: a tablefield with one column behaves as a listbox.

Remark

The attribute .multisel has become superfluous for tablefield and listbox by the attribute .selstyle, but .multisel will still be supported.
