I know this function brings a lot of information about the elements. I didn’t find documentation about it. But when and how to use it in practice? Could you give some examples of use? Can I change the value or just read values? ---

I’m sure there is a ton of use cases, but the two main use cases I’ve been using it for: 1. Targeting the element using it’s id. ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/c/c58c9e426710181f48690aa02f21536bb55dd890.png) When using custom JS in a workflow and targeting the element the workflow is running on via it’s id, using thisInstance.id is handy. 1. Getting the element’s position and sizing info. ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/d/de813f2f0554726519585d0c537295db4f414cb0.png) You can also do this via the advanced interactions, but it can get tricky when you have an element bound to a list and you only want to target the one that the workflow is running for. I’ve found using this more straight forward. ---

Thanks for the reply. What I struggle to understand is how to fill it ? What does it represent exactly ? Mine is always “empty” 😅 ---

In the base menu it’s always labelled as empty, but once you put in into the binding menu it’ll show it’s values ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/a/a056a89d0190f18e94289167f588485cb2a1aae7.png) ---

Same as @MatthewS Using it mostly when I import libraries with the NPM plugin. And then need to initialize instances on mount of my div 🙂 ![CleanShot 2024-07-24 at 11.59.22](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/a/a3048ffee3d6b5c526e8da80e45321ece0dd9064.png) ---

It was not meant for this. Can you tell more on what you are trying to achieve with the Date and Time Picker? ---

I need to change some properties of the element that are not possible dynamically, such as “mode” (Date, Datetime…) and even if possible, I can customize something ---

Got it. I guess what would answer your need would be to able to bind those properties. You can make a [feature request here](https://feedback.weweb.io/make-a-request/)!
