How to make a field appear based on value of another field.

[mateusz3]

Hi Guys,

I am struggling with this one.

I have two fields on the form:

-Difficulty

-New Ticket

What I need to do is to make the New Ticket field hidden on the form unless the difficulty field is Level 2

Any advice?

Regards

Matt, You're going to want to look into UI Policies for that form.

Example: Create a UI policy

Hi Matt,

You can have an ONchange client script.

check if the newValue == "Level 2", make the New Ticket visible by g_form.setDisplay("field_name",true);

else g_form.setDisplay("field_name",false);

Or write a Ui Policy even for on load if the value is not Level 2 then it should not be displayed and reverse if value condition

I would recommend using UI policy option here.

When possible, consider using a UI policy instead of a client script for these reasons:

• UI policies have an Order field to allow full control over the order in which client-side operations take place.
• UI policies do not require scripting to make a field mandatory, read-only, or visible.
