Elementor uses three main building blocks: Sections, Columns, and Widgets.
Sections are the largest building blocks, and inside them are groups of Columns. Columns sit inside of Sections and are used to house the Widgets. Widgets are placed inside of Columns.
You control the Section, Column, and Widgets with their handle.
You can choose to show or hide the editing handles by clicking the hamburger menu to open Elementor’s Style & Settings Configuration menu. Click the Preferences tab and slide the switch to Yes to show Editing Handles when hovering over the element’s edit button or No to hide the handles on hover.
