Multi-Form is an advanced option, which allows the developer to show a same form on a parent form as many times as required.
Similarly, Sub Form is a form added attached on a form using the Form Panel as a regular form items.
For Example: Consider the below information for creating a multi-form:
- Biller Info form – this form is the parent form containing a sub form with labels and a multi-form.
- Biller Label form – this form is a sub form just containing the labels Biller Name, Biller Amount, and the Area Code.
- Biller Detail form – this form contains the only 3 form items to capture the Biller Info but rendered on the parent form as many times using its Initial Multiplicity property.

BTN_CANCEL | Negative | 4 |
After configuring, write the handlers to launch the form on a menu click. See Showing the form on Menu click for more details.
The form should appear as shown:
To add an instance of the form, use the fm.addNext('FORM_ID') API as shown:
| Code Block | ||
|---|---|---|
| ||
CABR.registerHandler('BTN_ADD','CONT_BILLER_INFO', function (config){ this.fm = config.frmObj; |
...
this.fm.fm.addNext('BILLER_DETAILS'); |
...
}); |
To delete an instance of the form, use the fm.removeAt(formIndex,'FORM_ID'); API as shown:
| Code Block | ||
|---|---|---|
| ||
cbx.ns("my.listner.namespace"); my.listner.namespace.BillerInfoForm = Class(cbx.Observable, { |
...
constructor : function (config) |
...
{ this.fm = config.fm; |
...
}, |
...
registerHandlers : function () |
...
{ var formIndex=null; |
...
this.fm.registerHandler("cbxchange","OPT_BILLER", function(fm, event, fieldname, value, index, parent) |
...
{ //finding the index of the instance to be deleted formIndex=index; |
...
var count = fm.getNumberOfSubForms('BILLER_DETAILS'); for(var i=0; i<count; i++) |
...
{ if(i!=index) { fm.model.setValue('OPT_BILLER',"",false,i,parent); |
...
} } }); |
...
} |
...
}); |
...
CFLR.registerListener("BILLER_INFO", my.listner.namespace.BillerInfoForm); |
...
CABR.registerHandler('BTN_ADD','CONT_BILLER_INFO', function (config) { |
...
fm.removeAt(formIndex, 'FORM_BBAR_MULTI'); |
...
}); |
