        The `ui.splitter` element divides the screen space into resizable sections,
        allowing for flexible and responsive layouts in your application.

        Based on Quasar's Splitter component:
        `Splitter <https://quasar.dev/vue-components/splitter>`_

        It provides three customizable slots, ``before``, ``after``, and ``separator``,
        which can be used to embed other elements within the splitter.

        :param horizontal: Whether to split horizontally instead of vertically
        :param limits: Two numbers representing the minimum and maximum split size of the two panels
        :param value: Size of the first panel (or second if using reverse)
        :param reverse: Whether to apply the model size to the second panel instead of the first
        :param on_change: callback which is invoked when the user releases the splitter
