Component with Bootstrap navbar

Go to the Component properties  and change the presentation template to bootstrap4.

Right-click in Component in the Outline view, go to Add control to component and select Part page component.

Find the navbar component, give it a prefix of header_ and choose to embed it.

Embedding a component creates an editable copy of the original component. An embedded component is no longer linked to the original and is therefore unaffected by any changes made to the original. 

Test  your component in the browser.

Create a new form in VerjSamples and call it myComponent. 

Right-click in the Outline panel, go to Add control to page and select Part-page component. 

Find the header component, give it a prefix of p1_ and link it to your page.

A linked component is maintained independently of the applications that it's deployed to.

Save and run your form to see your header component appear. 

Create a new form and call it myComponent2. Add your header component to the form and save.

Go to your component and add a panel with a yellow background, or make any obvious change, and save.
