View vs Item-View
A card can have a View and an Item-View.
A Card can have two ways of displaying: a View and an Item-View. You can think of the latter as a mini-version of the former. The reason it is called Item-View, not mini-View, is that it is usually used in an itemised list. In TokenScript both are defined in the <card> element.
This table listed the typical content of View and ItemView for each type of cards.
|When used in||Typical content of a View||Typical Content of an Item-View|
|Token Card||Typically a detailed view of token attributes.||The most important information about the token. Take a DeFi token for example, an ItemView might only have balance and status (e.g. health factor in the case of AAVE token).|
|Activity Card||Detailed explanation of the activity.||An at-a-glance view of the activity.|
|Action Card||Typically, a form where users can type information.||A preview of such a form. ItemView of an ActionCard is not often used and usually not defined.|
View and Item-View of an Token Card
Often, for a TokenCard card, an Item-View is used first, and when the user clicks it, he gets to see the full view. It is almost always the case in user's wallet.
However, on a web page, its web developer can design where and whether Item-View or View should be used. In the below example, Item-Views of 2 Tokens (TokenCard) is used for user to choose which token to use for the payment. When the user chooses a Token, what opens is the "Pay" ActionCard, not the Token Card. The View of a TokenCard is unused at all.
