The OOTB feature of Dynamics Forms allows user to show and hide fields based on certain criteria derived; again from the fields. A very useful feature but not supported in communities. As a result projects end up redesigning and reworking the entire detail page layout in a custom way which becomes complex as the conditions grow.
Also, Dynamic Forms can only show/hide fields conditionally but cannot make them read-only conditionally. Also most of the community based project requires a wizard-cum-questionnaire structure wherein as the user updates the field, the next set of questions (fields) should be shown/hidden/made read-only based on certain conditions etc.
Introducing edf.
Extreme Dynamics Forms (hereafter referred as EDF) is a generic LWC component that can behave as Dynamic forms that work for Communities as well.
It leverages a client side Decision Engine built using pure Javascript that can compile and evaluate any configured boolean expressions against the record onto which the component is added and configured.
Features
- Dynamic Forms supporting communities.
- Conditionally show-hide fields and/or make fields read-only and vice versa based on criteria encompassing fields of the same record.
- Easy setup - Quickly generate form definition records derived from any existing page-layout of an object with a button click.
- Configure conditions in the form of complex boolean expression including brackets
(, )for precedence e.g.(custom_field1__c = “some text” && standardField1 == 100) || custom_field1__c = “some other text” - Supports fields in both LHS and RHS of an expression [Not supported in OOB Dynamic forms].
- Supports parent fields in expression.
- Supports composite fields viz. Name field on Contact and Address fields in expression. E.g.
- Component configuration is quick - simply drag and drop on the record detail page layout and select the Form Definition Version.
- Decision engine works seamlessly on load and also on change of fields value on the fly.
- No server calls since the decision engine runs completely at the client side - making the overall experience performance rich.
- Not just fields - EDF can also be configured to conditionally toggle sections (containers).
- Can be extended to implement client side validation using HTML snippets as Form elements.
- Custom Label for fields.
- Conditional labelling of fields.
- Debug Mode for Admins.
- Support for Multi-Select picklist field in expression. Use
~and!~operators that work as includes/contains and doesn't include/doesn't contain respectively.
