Say you have a checkbox field, and you want to know if a particular option has been checked. Here is the JS to do it.

Example:

Fieldname: ManagerList

Manager to test for: 33

Items currently checked: 33, 34

Syntax:   '[ManagerList]'.indexOf("33") != -1

This means, starting at position 0 in the string of chosen options, the position of the first occurance of "33" is not -1

Otherwise you could easily get

- [ManagerList] returns 33,34
- [ManagerList:JsonArray] returns ["33","34"]

------------

Also

I think you can use the syntax

[CheckboxList].includes('Other')

in the Bind Expressions / Show of the optional field.

.toggle {margin: 0px 0 0px; }

.bstrap30 .row {​ margin-right: -84px;margin-left: -22px;}

</style>

Setting fields to Display:none hides them but the row that they are in still takes up vertical space. When you want to collapse that space, add the following
