How to hide the title of a variable set

[M_Tomy]

Dear Experts.

I have a requirement to show or hide certain variables under certain conditions.
So I have used "g_form.setVisible" in the UI policy to hide the variables in the catalog task.
However, I am having trouble seeing the title of the variable set to which the hidden variable belongs.

I would like to hide the title of the variable set without using the SysID of the variable set if possible.
Please let me know if you have any insight.

Hello, i know it is already a year and more later as a response, but i think it can help someone, having the same requirement.

My requirement was to hide the "title" field from a MRVS (Multi-Row variable set), so i completed the task using a "onLoad" client script with following code, without manipulating the DOM, using only OOTB method of g_form: 

function onLoad() {
   g_form.setLabelOf("<name_of_MRVS>",  ""); 
}
