You can indent items in a Multicolumn Listbox to represent hierarchal data (similar to a Tree without the ability to expand and collapse) by causing the item's symbol to indent. To indent the symbols use the following equation: | |||
{| | |||
|- | |||
| <code>Index to Set = Orginal Item Symbol Index + Indent Level * 65536</code> | |||
|} | |||
The 65536 shows that you can only have <code> 2 ^ 16 = 65536</code> symbols in a Multicolumn Listbox (0 to 65535). However, only 0 to 40 have default values. | |||
