Hi Arpit, glad to see your playlist to learn Power Pages in deep.
I have a question though, is it possible to use multiple web templates in single page? Or could you please help me figure out the approach of having multiple reusable modules in a page (dashboard page with multiple modules) so that I can create modules as a web templates and use the same module code in other pages as well. your help is appreciated.

This is a great session Arpit. I have a question. I am trying to set a dropdown value in general validation. I have a Multistep form. It has 2 steps and in Portal management, on 2nd step--> Form Options tab, under custom javascript, I have written JS. it is not able to alert the dropdown value. The only difference I see from your demo is, you have written in Basic form and I have written in Multistep Form Step Form itself. Please suggest.

if (window.jQuery) {
(function ($) {
if (typeof (entityFormClientValidate) != 'undefined') {
var originalValidationFunction = entityFormClientValidate;
if (originalValidationFunction && typeof (originalValidationFunction) == "function") {
entityFormClientValidate = function() {
originalValidationFunction.apply(this, arguments);

return false;
};
}
}
}(window.jQuery));
}
