Entering data: Drop-down lists

You can use the Insert > Drop-Down Lists dialog box to enable displaying drop-down lists for the current field(s) and/or to manage (create, edit, delete) lists in the current workbook.

When editing a cell with a drop-down list attached to it, GS-Calc opens a windows with a list of values with checkboxes and you can quickly choose predefined field values instead of re-typing them.
Pressing the cursor keys Up (in the first line of that edited field) or Down (in the last line of that edited field) switches the "focus" to the displayed list window. To switch back to the edited field, scroll the list to its first item and press Up or simply click the edited field.

To scroll the list, use the standard cursor keys: Up, Down, PgUp, PgDn, Home, End. If a list has multiple columns you can also use Left, Right to jump between columns.

To (un)check a given list item, press Space or click the check-box. If the "multi-selection" option is disabled for a list, the check-box button of the current list item is always "on" and checking another one always automatically unchecks the previous one.
To accept selected list item(s), press Enter, double click (one of) the selected list item(s) or click the "OK" button displayed above the edited field.

You can display list items in 1 to 99 columns. Dragging the vertical grid-lines in the list window resizes all these list columns. To resize the list window drag its bottom-right corner or its edges.

To create a new list click the New List button and to add new list items, enter or paste them in the List Items edit field: one item in one line.

The maximum number of list items is the same as the maximum number of rows: 12 millions.

If you select the AutoAppend option, each new unique value entered in the corresponding field(s) will be added to the list automatically.

If you choose the AutoComplete option, the edited cell contents will be automatically completed/replaced with the full found matching text from the list after you type the initial characters.

If the Sort items option is not selected, the list will display all its elements in the same order as they were added/entered. Otherwise the list items will be sorted before displaying.

One list can be used by any number of cells in any worksheets in a given workbook. You can create up to 100 list in one workbook (file). To move lists between workbooks, you have to copy/paste the data from the List Items edit field.

Note:
If you specify the "columns" to be > 1, the splitter lines are displayed only if the list items occupy more than one column. Thus to resize columns you might need to temporarily shrink the list window, for example:
