==What is a container?==
A container is a Vision2 widget that may contain other widgets. Some containers such as [[ref:libraries/vision2/reference/ev_cell_chart|EV_CELL]] may only hold one widget while containers such as [[ref:libraries/vision2/reference/ev_box_chart|EV_BOX]] may hold multiple widgets. As a container is of type [[ref:libraries/vision2/reference/ev_widget_chart|EV_WIDGET]] , this means that a container may be placed within a container. Windows inherit from [[ref:libraries/vision2/reference/ev_cell_chart|EV_CELL]] and are therefore classed as containers also.
