FormToolbar | Simple , movable powerful toolbar for UITextField | iOS library

I have a child layout and parent layout like as following. I need to select multiple items in a child layout. I can able to select multiple items but facing two issues. 1.On scrolling the selected item is changing. 2.When i am selecting the item at first row, the item 4 row is also selecting.

Here is my code.

Parent layout:

I'm currently working on a project and using admin-on-rest. The Resource component has been very helpful so far, it's so easy to build views to list, view, create and edit items. But there has been coming up some situations, where there isn't a need for the Resource component and mapping the API endpoint to certain urls in AOR.

On this project there's a settings page for example changing the website language. Now I also would like to add there a form for editing customer data. The AOR documentation has examples, where SimpleForm component is inside Edit component, but I can't do it that way, because using it throws errors. I don't know yet the exact reason for those errors, but I guess it is related to that, that I'm not using the Resource component that would map the correct API endpoint for the Edit component to use.

First I had a problem that how to get the customer data to a SimpleForm component without using the Resource component. I solved that by adding a rest call to the componentDidMount method, and setting the response to the state. Using the state the SimpleForm component can display the correct customer data. The SimpleForm provides a Save button by default, but I also found out that I can override that using a toolbar prop.

My code so far:

This is my iframe and it contains lots of tables.

I am trying to use iframe[src^="/Lists/Interne%20nyheder/DispForm.aspx"] but it don't seem to work on my page.

If I remove it from my css then the code below works just fine.
