CRM 2011 Show/Hide sections based on a specific optionset value - javascript

My request was that based on a optionset value I had to show only a specific section from a tab and hide the rest. Each optionset value had a specific section and the section label started with this optionset value. So my condition to show the section was - section name starts with "optionset value".


function ShowHideSectionsBySubject() {

    var tabName = "tab_Name";

    var sectionPicklistValue = Xrm.Page.data.entity.attributes.get("optionset_field").getValue();
 
    var sections = Xrm.Page.ui.tabs.get(tabName).sections.get();
    $(sections).each(function (index, section) {
       //hide section
        section.setVisible(false);
        if (sectionPicklistValue != null) {
            if (section.getLabel().startsWith(sectionPicklistValue.toString())) {
                section.setVisible(true);
            }
        }
    });
}
