Adding Tooltip for input field

Hi.

Is it possible to add a tooltip to an input field in a form so when a user clicks on the form he/she knows the valid format. Also I would like to provide the tooltip when validation fails on a specific field.

If a tooltip is not possible what is the best way to display some text to the user on the fields that are invalid?

Thanks
Nick

It can be done with custom item type create. Please find more information here docs.dhtmlx.com/doku.php?id=dhtm … ustom_item
