Full Width Column SPFx Control

SharePoint Online Modern communication site pages support section layout, named Full-Width column. It helps to span the section without any horizontal margin or padding.
In this article, you will learn the following,
  1. Add Full-width Section.
  2. Add Full-width support to SPFx Control.
  3. Add SPFx Control to Full-width Section.
Users can choose from a number of different section layouts such as,
  • one columns 
  • two columns
  • three columns
  • one-third left column
  • one-third right column

Full-Width Section Requirement

When we build a regular SPFx control, it doesn’t expand beyond a certain width due to section layouts which don’t support or allow the full width.
So, let’s get started
Step 1 - Add Full-Width Section
  • Full-width section allows layouts to expand to the full width of the page.
  • Edit the page
  • Click the plus “+” icon parallel to the section layout and select the Full-width section.

Step 2 - Add Full-Width support to SPFx Control
SPFx control doesn’t add the full-width column property by default. But SharePoint Framework allows us to add full-width column attributes into the web part manifest file, i.e., GetEmployeeDataWebPart.menifest.json and adds supportsFullBleed property to true.
