How to customize the DrawerItem using the lib mikepenz/MaterialDrawer

I am using the lib MaterialDrawer (https://github.com/mikepenz/MaterialDrawer).

I would like to use the side bar on the right as the filter section like Foursquare filter:

But I noticed that there are only SectionDrawerItem.java, SwitchDrawerItem.java and ToggleDrawerItem.java that defined toggle and switch. But they are not enough to define the filters. I would like to ask if I can define my own layout for the sidebar or add more options to the DrawerItem? Thanks in advance!

The easiest solution is to extend one of the existing DrawerItems, but this only works if you do not need a completely different item.

A CustomDrawerItem is already shown in the sample application

public class CustomPrimaryDrawerItem extends PrimaryDrawerItem {

    private ColorHolder background;

    public CustomPrimaryDrawerItem withBackgroundColor(int backgroundColor) {
        this.background = ColorHolder.fromColor(backgroundColor);
        return this;
    }

    public CustomPrimaryDrawerItem withBackgroundRes(int backgroundRes) {
        this.background = ColorHolder.fromColorRes(backgroundRes);
        return this;
    }

    @Override
    public void bindView(RecyclerView.ViewHolder holder) {
        super.bindView(holder);

        if (background != null) {
            background.applyToBackground(holder.itemView);
        }
    }
}

If you need more customization just implement the IDrawerItem interface and implement the methods. An easier DrawerItem which implements the AbstractDrawerItem which comes with a few predefined methods and properties is the DividerDrawerItem

public class DividerDrawerItem extends AbstractDrawerItem<DividerDrawerItem> {
    @Override
    public String getType() {
        return "DIVIDER_ITEM";
    }

    @Override
    @LayoutRes
    public int getLayoutRes() {
        return R.layout.material_drawer_item_divider;
    }

    @Override
    public void bindView(RecyclerView.ViewHolder holder) {
        Context ctx = holder.itemView.getContext();

        //get our viewHolder
        ViewHolder viewHolder = (ViewHolder) holder;

        //set the identifier from the drawerItem here. It can be used to run tests
        holder.itemView.setId(getIdentifier());

        //define how the divider should look like
        viewHolder.view.setClickable(false);
        viewHolder.view.setEnabled(false);
        viewHolder.view.setMinimumHeight(1);

        //set the color for the divider
        viewHolder.divider.setBackgroundColor(UIUtils.getThemeColorFromAttrOrRes(ctx, R.attr.material_drawer_divider, R.color.material_drawer_divider));

        //call the onPostBindView method to trigger post bind view actions (like the listener to modify the item if required)
        onPostBindView(this, holder.itemView);
    }

    @Override
    public ViewHolderFactory getFactory() {
        return new ItemFactory();
    }

    public static class ItemFactory implements ViewHolderFactory<ViewHolder> {
        public ViewHolder factory(View v) {
            return new ViewHolder(v);
        }
    }

    private static class ViewHolder extends RecyclerView.ViewHolder {
        private View view;
        private View divider;

        private ViewHolder(View view) {
            super(view);
            this.view = view;
            this.divider = view.findViewById(R.id.material_drawer_divider);
        }
    }
}
