Hi @sirishap9577191 

   You can add class in dropdown and based on that trigger JS function to hide/show tabs.

sharing code snippet

/*globals Granite,Coral*/
(function ($, document) {

        'use strict';

        //used in the dialogs
        $(document).on('dialog-ready', function () {
            init()
        });

        var visibaleTabIds = [];

        function toggleTabs(allDepPanelIds, negate) {
            return function (tab) {
                var panelStack = tab.parentElement.parentElement;
                var tabId = panelStack.id;

                visibaleTabIds.push(tabId);
                var tabsList = document.querySelector('coral-dialog-content coral-tablist');

                tabsList.items.getAll().forEach(function (tabItem) {
                    var ariaControls = tabItem.getAttribute('aria-controls');

                    if (allDepPanelIds.indexOf(ariaControls) !== -1) {
                        if (negate) {
                            tabItem.hidden = !ariaControls !== tabId;
                        } else {
                            if (ariaControls !== tabId) {
                                tabItem.hidden = !visibaleTabIds.includes(ariaControls)
                            } else {
                                tabItem.hidden = false;
                            }
                        }
                    }
                });
            };
        }

        function showHideTabListItems(initial) {
            var allDependentTabsNodeList = document.querySelectorAll('[data-dep-value]');
            var allDependentTabs = [].slice.call(allDependentTabsNodeList);

            var allDepPanelIds = allDependentTabs.map(function (tab) {
                var panelStack = tab.parentElement.parentElement;
                return panelStack.id;
            });

            var tabsToShow = allDependentTabs.filter(function (el) {

                var array = el.dataset.depValue.split(',');
                if (array.length) {
                    return array.includes(initial);
                } else {
                    return el.dataset.depValue === initial;
                }

            });

            if (tabsToShow.length) {
                tabsToShow.forEach(toggleTabs(allDepPanelIds, false));
            } else {
                allDependentTabs.forEach(toggleTabs(allDepPanelIds, true))
            }

            visibaleTabIds = [];
        }

        function setUpShowHide(selector) {
            Coral.commons.ready(selector, function () {
                selector.on('change', function (e) {
                    showHideTabListItems(e.target.value);
                });

                var initial = selector.value;
                showHideTabListItems(initial);
            })
        }

        function init() {
            Coral.commons.ready(document, function () {
                var selectors = document.querySelectorAll('.tabs__show-hide');
                if (selectors.length !== 0) {
                    selectors.forEach(setUpShowHide)
                }

            })
        }
    }

)(Granite.$, document);

Hi @sirishap9577191 ,

Please check if this works for you. I have tried to hide a second tab based on the dropdown selection. In dropdown selection node I have added granite:id - dropdown-selection property, and in tabs node i have added granite:class - dropdown-tab-container

(function ($, document, ns) {
    $(document).on("dialog-ready", function() {	
        function showHideTab() {
            var dropdownSelection = $("#dropdown-selection").val();
            var coralTab = $(".dropdown-tab-container coral-tablist coral-tab");
			
            if (dropdownSelection === "default") {
                coralTab.eq(2).hide();
            } else {
                coralTab.eq(2).show();
            }
        }

       $("#dropdown-selection").on("change", showHideTab);
       showHideTab();
	   
    });
})(Granite.$, document, Granite.author);
