Re: How to properly append/replace DOM elements using just karax

[NerdRat]

I have solved the issue the karax way, to produce a new element and get it 
render, I created each element using `VNodeKind`, to make the button "create" 
the new element, I simply save the previously selected option `VNodeKind` and 
createt with `newVNode`, wrapped in `buildHtml()`:
    
    
    var
        prev: VNodeKind
        selected: VNodeKind
    
    proc renderElementList*: VNode =
        result = buildHtml(tdiv):
            select(id="selector"):
                proc onchange(e: Event, n: VNode) =
                    prev = parseEnum[VNodeKind]($n.value)
                for element in low(VNodeKind) .. high(VNodeKind):
                    option(value = $element):
                        text $element
    
    proc renderElement*(kind: VNodeKind): VNode =
        result = buildHtml(newVNode(kind))
    
    proc renderCreator*: VNode =
        result = buildHtml(tdiv):
            renderElementList()
            button:
                text "Create"
                proc onclick(e: Event, n: VNode) =
                    selected = prev
                    echo $selected, " created"
                button:
                    text "Edit"
                    proc onclick(e: Event, n: VNode) =
                        echo "Editing ", $selected
                tdiv:
                    renderElement(selected)
    
    Run

This solution is not genius but it does the job.
