I've added a check for a 'limit' property set on the fieldConfig node under the multifield. If present & not zero, it will use this as the max number of fields a user can add.
In the constructor (line #53), add in a check to get the value of limit from the fieldConfig node:
==============================================================================
######################################################
##
## if (!config.fieldConfig.limit) {
## config.fieldConfig.limit = "0";
## }
##
######################################################
In the handler for the "+" button (line #71) change the function to the following:
==================================================================================
################################################################################################
##
## if(config.fieldConfig.limit == 0 || list.items.getCount() <= config.fieldConfig.limit) {
## list.addItem();
## } else {
## CQ.Ext.Msg.show({
## title: 'Limit reached',
## msg: 'You are only allowed to add ' + config.fieldConfig.limit +
## ' items to this module',
## icon:CQ.Ext.MessageBox.WARNING,
## buttons: CQ.Ext.Msg.OK
## });
## }
##
###################################################################################
Rather than removing the buttons, I've just created a pop-up to inform the editor that 'N is the max number of fields allowed'.
