    Default Unanswered: Displaying items from nested list view

    Unanswered: Displaying items from nested list view


    hi there,
    hoping someone can help with this barrier.

    Ive been working off an example I ve found to parse json data into a listedNestView.

    I cant seem to get it to display the current item when selected.

    Can anyone fill how I can do this?
    thanks

    here is my code
    Code:

    I wasn't getting any errors, but I've made progress on this.

    I can now display the list, and go to a view item, im now trying to style this up.

    What im interested in knowing is how to apply a template or style my result
    Code:
    detailCard.setValue(show)
    so I can display an image, with text and links etc

    My complete source is:
