- A step-by-step guide on how to add a custom help menu to the header to serve as inspiration for other custom components that can be added
Steps
Customise your app manifest
This is an app-level setting. When adding a component to the STORE or OMS header bar, a customised manifest is required. The manifest name should follow the format 
`fc.mystique.manifest.<web-app-name>`. Here is an example of how to add a customised OMS manifest:Build out the custom help menu component
First we will build out the new help menu to be included in the header. See below for some sample code to get you started.Make sure to add the component to the registry! Your export should look something like:
`ComponentRegistry.register(['custom.helpMenu'], HelpMenu, { category: 'content' });`Next we will add the header field into our root level manifest
To add components into the header bar you must first add the
`header` field at the root level in the manifest. Multiple components can be added within the `desktop` and `mobile` fields. Here is an example of the `header` configuration:There is no limit to the number of components that can be added, so screen size should be taken into account. Adding too many components may overrun onto adjacent components.Now we will configure the position of the help menu
Component alignment can be specified using the
`position` field. Alignment options include 'left', 'right', 'center', or 'centre'. The `position` field is not mandatory; if it is missing or contains an invalid option, the default alignment is 'left'.Finally we will add the component configuration
Add our
`HelpMenu` component from the previous steps to the configuration. Because we want the help menu to be available on both desktop and mobile we add the configuration to both.Results
The result of adding our help menu component will look like this on desktop:
And on mobile devices it will look like this:
