Hi All,

How to set a required DFF on contracts using Page Composer based on the Contract Type field?

On the Contract Overview page, we have the Type field. Depending on the value of this field type, we want certain descriptive flexfields to be required, depending on the contract type.

Can we do this using Page Composer EL Expression?

For example:

If the contract type is "Confidencialidad" we want the descriptive flexfields "Número de licitación" and "Número de cotización" to be required.

If the contract type is NOT "Confidencialidad" we want the descriptive flexfields "Número de licitación" and "Número de cotización" to NOT be required.
