How to restrict your component to one or more objects?

Hi ,

We can restrict to our component to one or more objects by using the following:

<sfdc:objects> and <sfdc:object>

Here in the following example we are restricting the component to Opportunity which is using the following design component by using  <sfdc:objects> and <sfdc:object>.

<design:component label="Hello World">

    <design:attribute name="subject" label="Subject"/>

    <design:attribute name="greeting" label="Greeting" />    

    <sfdc:objects>       

        <sfdc:object>Opportunity</sfdc:object>

    </sfdc:objects>

</design:component>

If we define the design component with lightning component as above then it will be available for Opportunity Lightning Record page only.
