I am using sap.m.multicombobox within a page and that page has footer. I am placing this multicombobox in the page header.Now if I click the multicombobox dropdown button then it will show all the suggestions and this is blocking the footer buttons. So I want to limit the size of dropdown suggestions without setting the suggestion limit. if there are more suggestions dropdown should come but it should be there within footer content.
There is no property directly avaialble to set the size of the dropdown. There is a way to do it, but let me warn you that it is not the standard approach to do it. When you try to select a value inside a Combobox/MultiCombobox, it will create a Popover control inside which is a List control. You can set the height to this Popover by getting the reference to the internal Popover control.
var oCombo = this.byId("MyComboBox"), oPopOver = oCombo.getPicker(); oPopOver.setContentHeight("400px"); //Set height accordingly
