Remove a ListElement from the ListView without removing it from the model

[DavidM29]

Hello,

I do have a list of component. That list is defined by a JS Model.
I would like to handle the visibilty of some elements without removing the elements from the model.

I fact I do save some param via the index of the model and if I remove it it will make all my saving function obselete.

Here is an example of what if have :

property var model:
    [
       {"type": "switch", "optionName": qsTr("Option 1")+trans.emptyString, "value" : option1Value},
       {"type": "switch", "optionName": qsTr("Option 2")+trans.emptyString, "value" : option2Value},
       {"type": "input", "optionName": qsTr("Option 3")+trans.emptyString, "value": option3Value}
    ]

ListView {
            id: dataView
            clip: true
            spacing : 2
            model: window.model
            delegate: OptionDelegate{}
            interactive: false
        }

What I have tried is that I use a property in my model called visibilty for example. And I use this property in order to change the visible property of my delegate. It work I don't see my delegate anymore but it leave a blank in the list and I don't want that.

Is there anyway to handle this ?

hi,

maybe you can try to set height to 0 when you set visible to false

height : visible ? theHeight : 0
