How to set size of GlideModalForm?

[John Rissone]

I'm using GlideModalFormV3 and there doesn't seem to be a way to size the thing as there are no documented APIs to do this.

We can hack it via the callback and add the class "modal-lg" to the ".modal-dialog" node, but then the modal snaps after it loads to the smaller size and looks terrible.

With the new SN mandate to not use Jelly UI Pages, I'm out of ideas.

There is a .setWidth function. Don’t see anything about set height but with bootstrap that should be dynamic.

try doing below

var d = new GlideModalForm('dialog title', 'table_name_or_form_name', [callback on completion of submit])
         d.setPreference('name', 'value');
d.setWidth("300"); 
         d.render();

you can also add height like below

d.setWidth("95%");
d.setHeight("95%");

For the GlideModalForm object, there is no setHeight function, and the setWidth function is hardcoded to return 'modal-95', no matter what you pass in.

GlideModalForm.setWidth:

ƒ (width) {
this.setSize(width);
}

GlideModalForm.setSize:

ƒ (width) {
this.size = 'modal-95';
}
