Inkey, May 15, 2020 6767 Views

The Web Form Metadata contains additional behavior modification logic to augment or override the functionality of form. It allows portal admin to further configure entity forms and web forms such as predefined values and enhancing fields. In this blog, we are going to cover the very first type of metadata property i.e., “Attribute” with it’s properties and functionalities. We will cover the others in the next blog.

Steps to add new metadata in Web Form and Entity Form are as follows:

Add a new metadata in Web Form:

• On the Web Form Step which you want to modify, go to Related > Metadata

• Select New Web Form Metadata.

 

Add a new metadata in Entity Form:

• On the Entity Form which you want to modify, go to Entity Form Metadata

• Select New Entity Form Metadata.

Types of metadata:

There are 6 types of metadata, listed below:

• Attribute
• Notes
• Section
• Subgrid
• Tab
• Timeline

 

• ATTRIBUTE

Selecting “Type” as “Attribute” provide us the relevant options to modify the fields on the current entity form and web form.

“Control Style” section is used to modify the style and functionality of an attribute’s field.

“Prepopulate Field” section is used to assign the default values to specified fields on form load.

Below listed tasks can be performed through this section:
