Hi everyone, I'm trying to implement a feature that needs to go through view's items and with each item, I need to go through its props. Initially, I thoguht I could be able to handle it with a OnStartUp Event, and use a script for it, using something like: ```auto aux_list = [] for item in view: try: aux_list.append(item['props']['params']['tag']) #Here I'm trying to access the item's props/params/tag except: pass #After that, I would be able to send this aux_list to what I want to do. ``` Is it possible? I found some solutions for Vision, but idk how to proceed in Perspective with it. ---

This may be helpful > [@Iterate through all components programatically in Perspective?](https://forum.inductiveautomation.com/t/iterate-through-all-components-programatically-in-perspective/32938): > > I was wondering if there's a way to iterate through all components on screen for a perspective view? I was trying to use getRootContainer and getChildren but it doesn't seem as straight forward as I thought/as it was for Vision. Any know how this is done? ---

Very helpful, but I didn't find a way to access the items of another view, just using the self.view.rootContainer.children, but I want to pass the view path and go through its items instead, not just the self view. ---

You would have to obtain a reference to the actual view instance. There's no exposed way to do that for any arbitrary view path. From a live _session_ object, you have a `getPages()` method, and each Page has a `getViews()` method. ---

I know I could just put manually as a parameter on MainView, but this functionality of going throught the views would optmize the maintence and future upgrades. ---

Was there a question in there? 🙂 ---

Of course, I want to see if its possible to make a list of views as we have in Vision with **system.gui.getWindowNames()** ---

Yes, I thought it was already discussed above. [https://docs.inductiveautomation.com/display/DOC81/system.perspective.getProjectInfo](https://docs.inductiveautomation.com/display/DOC81/system.perspective.getProjectInfo) One of the keys is `views`. ---

> [@Roberto\_Luis](#): > > I know I could just put manually as a parameter on MainView, but this functionality of going throught the views would optmize the maintence and future upgrades. I'd argue that simple manually configured options/buttons make maintenance/upgrades easier than complicated scripts.They don't require as much documentation or knowledge of scripting functions.
