Types of blocks
1. Scroll past the cover. Next to Tell your story, click on Add icon to integrete a new content block.
The block palette contains options for adding content. You'll tell your story using these blocks to add sections of content to the body of your story.
There are a few types of blocks you can choose from. There are Basic , Media and Immersive.
Immersive blocks are unique in that they become full-screen takeovers of your story, providing different, interactive reading experiences.
As you can see, some of the options are greyed out. These options are only accessible with an organization account. As we used a public account here, ArcGis shows us that these options cannot currently be used (Image gallery, Audio, Embed and Timeline).
A storymap created with an organization account may contain these blocks. If you want to make changes to such a storymap, you can only do so on the blocks you have access to as a public user. If you delete one of them, you will not be able to create it again.
Note that you can change all type of blocks position with drag and drop:
