- Showon Attribute. Conditionally show or hide the field depending on the value of other fields. The syntax to use here, for example:
- list-of-items – It is the name of an already created field on which this field will depends to be show.
- value1 – Is the value need have the field on which it depends to be show.
- [OR] – To create a choice among multiple fields. In the example, this field will show when list-of-items field have the value: value1 OR value2
- [AND] – To combine multiple fields. This field will show only when list-of-items field have the value: value1 AND value2
- You can also use value 'does not equal' as in list-of-items!:value1. The syntax will show this field only when list-of-items is not equal to value1
- To show this field when list-of-items field has been selected and have not a empty value, use the syntax list-of-items!: (without a value specified).
- Note: Subform fields handle different the identifier name of list-of-items. If you create a Subform custom field and you add this conditional field you are creating to there, you need use field[ID] instead of list-of-items, where ID is the id of the field list-of-items. Therefore, the showon attribute for this conditional field you are creating need be:
