How do I add elements/sectors to views container using a custom button in the Panel

@AbdiasM @ko06 sorry for being late on this! based on #277

        const pn = editor.Panels
        let editPanel = null
        pn.addButton('views', {
            id: 'editMenu',
            attributes: {class: 'fa fa-address-card-o', title: "Edit Menu"},
            active: false,
            command: {
                run: function (editor) {
                    if(editPanel == null){
                        const editMenuDiv = document.createElement('div')
                        editMenuDiv.innerHTML = `
                        <div id="your-content">
                             Input: <input/>
                             <button>Button</button> 
                              <!-- eg. bind a click event on button and do something with GrapesJS API -->
                        </div>
                    `
                        const panels = pn.getPanel('views-container')
                        panels.set('appendContent', editMenuDiv).trigger('change:appendContent')
                        editPanel = editMenuDiv
                    }
                    editPanel.style.display = 'block'
                },
                stop: function (editor) {
                    if(editPanel != null){
                        editPanel.style.display = 'none'
                    }
                }

            }
        })

Cheers!
