It is possible to save any element with custom element parameters as My Element. These elements will appear in the Add Element window under the “My Elements” tab. To create your custom element, add an existing element to the page, set your own parameters and click on the “gear” icon in the upper-right corner of the element edit window.
It is possible to remove already created custom elements if you click on the “Manage Elements” buttons in the “My Elements” tab.
