Component only builds tree after initial mount and not on re render.

[iantbutler01]

Right now if you have to programmatically update the sidebar as in the case of the adding new sections they do not render because the tree is only built once right after the component mounts.

[iantbutler01]

Got around this by hashing a property of the sections and setting the hash as the SideMenu's key attribute so when the sections change the key changes and forces a component rebuild/remount This is fine for my case as I don't imagine super-frequent changes so rebuilding the tree every time while not the fastest isn't a concern for me but it could be for other people.

@GrandathePanda you are talking about the JSON config right? This would be a nice feature indeed. Could you maybe open a PR or send a gist?

The component is rebuilt if you pass a new array. If you mutate the old one the reference stays the same and the tree does not rebuild.

That was not true for me and on react's re-render I am constructing a new array each time. Below are the contents of my render.

let items = [{divider: true, label: "Documents", value: ""}];

        const buildDocs = (acc, _document) => {
            const doc = this._document(_document);

            acc[0].push(doc.ssmlSha);
            acc[1].push(doc);

            return acc;
        }

        const [shas, docs] = this.props.documents.reduce(buildDocs.bind(this), [[], []]);

        items.push(...docs);

        let key = shas.join("");

        return (
            <SideMenu key={key} items={items} activeItem={""}>
            </SideMenu>
        )
