Creating a custom Lightning component requires programming skills. Or, you can install an existing Lightning component from the AppExchange.
To learn how to create a custom Lightning component, see the Lightning Components module.
Custom components in your org that are configured for use in the Lightning App Builder appear in the Lightning Components pane.
- Configure the component and its component bundle so that they’re compatible with the Lightning App Builder and Lightning pages. For details, see the Lightning Components Developer’s Guide.
- Deploy My Domain in your org.
The custom component we’re providing for this module has already been configured for the Lightning App Builder. Before you can use it, however, you need to take care of step 2.
If you already have My Domain enabled in your DE org or use a Trailhead Playground org, skip this section and the next one. You already have My Domain set up.
If you don’t have a subdomain yet, it’s easy to set one up.
Every Salesforce org is set up within the salesforce.com domain with a URL like https://na30.salesforce.com. With My Domain, you define your own domain, or a subdomain, within the salesforce.com domain. Your new URL looks something like: https://yourDomain.my.salesforce.com.
Use the My Domain wizard to create a subdomain.
- From Setup, enter My Domain in the Quick Find box, then select My Domain.
- Enter the name for your subdomain after https:// and click Check Availability. Typically, a subdomain is your company name, but you can use any name as long as it’s unique. If this name is already taken, choose another one.
- Click Register Domain.
Salesforce updates its domain registries with your new subdomain. When it’s done, you receive an email with a subject like, “Your Developer Edition domain ready for testing.” It takes just a few minutes.
Click the link in the activation email to log in to your Salesforce
subdomain. It takes you to your Salesforce
Notice that the URL in the browser address bar shows your new subdomain name. Right now, you’re the only one who has this URL.
- Click around your org to make sure that links point to your new domain. You probably haven’t created links in your DE org, so we can go on. (When creating a domain in a production org, this important step is easily overlooked.)
- From the My Domain page, click Deploy to Users, and then click OK. Deploying a subdomain rolls out the new subdomain URL throughout your org. Now all your users see the subdomain URL in the browser address bar.
- Step 4 of the wizard displays configuration options, which we can ignore for now.
We’ve provided a custom Opportunity Alert Lightning component that you can add to your Lightning page. Let’s install it into your org.
- Copy and paste https://login.salesforce.com/packaging/installPackage.apexp?p0=04tj0000001mMYP into the navigation bar of your browser, and then press ENTER.
The installation takes a few moments.
- Click Done.
After the installation completes, it’s time to add the component to your page.
- From Setup, enter App Builder into the Quick Find box, and then click Lightning App Builder.
- Click Edit next to the Top Accounts and Opportunities page.
- Add the OpportunityAlert component above the List View component.
In the properties pane, change Days Since Last Modified to
Did you notice that the text inside the component changed to match the new field value?
All right! The changes you made are immediately available in Lightning Experience and the mobile app. Let’s see what the page looks like now.
- Open the app on your mobile device.
- If necessary, log in using your Developer Edition credentials.
Go to the Top Accounts and Opportunities page.
Go back to your DE org and view the Top Accounts and Opportunities page in
Because you created the page using the Two Columns template, it uses the two-column format when you view it on the desktop or a tablet.
You’ve got the skills now to make the Salesforce mobile app and Lightning Experience handier and more powerful for your users. Go forth and customize!
