Hi!
I try create new widget for Visual Composer versrion 5.2
i found this https://wpbakery.atlassian.net/wiki/spaces/VC/pages/524362/Nested+Shortcodes+container
So i create some example widget:
It’s like that 
i can’t edit or add nested element
Standard Visual Composer Tabbed Content works fine ( see on screen “Zakladki” )
Hey,
Nested items are different.
You want to add the options to have gallery items?
I want to do exactly the same as in example:
[your_gallery param=“foo”]
[single_img img=“3012” title=“title”]
[single_img img=“3011” title=“title”]
[single_img img=“3013” title=“title”]
[/your_gallery]
So in Visual Composer i add New Element: Gallery then i can add new element Single Img inside Gallery component it’s much similar to Tabbed Content
That requires a different model of button, s you can run such type of element. Yes it is tabbed content.
Exmaple of the usage
vc_map(array(
"name" => __("Animated Headline Box", "mk_framework"),
"base" => "mk_animated_box_headline",
"content_element" => true,
'icon' => 'icon-mk-content-box vc_mk_element-icon',
"as_parent" => array('only' => 'mk_animated_box_txt_headline'),
"category" => __('Slideshows', 'mk_framework'),
'params' => array(
array(
"type" => "textfield",
"heading" => __("Extra class name", "mk_framework"),
"param_name" => "el_class",
"value" => "",
"description" => __("If you wish to style particular content element differently, then use this field to add a class name and then refer to it in Custom CSS Shortcode or Masterkey Custom CSS option.", "mk_framework")
)
),
"js_view" => 'VcColumnView'
));
vc_map(array(
“name” => __(“Animated Headline Item”, “mk_framework”),
“base” => “mk_animated_box_txt_headline”,
“as_child” => array(‘only’ => ‘mk_animated_box_headline’),
‘icon’ => ‘icon-mk-content-box vc_mk_element-icon’,
“content_element” => true,
“category” => __(‘Slideshows’, ‘mk_framework’),
‘params’ => array(
array(
"type" => "toggle",
"heading" => __("First Element", "mk_framework"),
"param_name" => "item_first_element",
"value" => "false",
"description" => __("Activate if that is your first element only", "mk_framework")
),
array(
"type" => "textfield",
"heading" => __("Text", "mk_framework"),
"param_name" => "item_txt",
"value" => "",
"description" => __("", "mk_framework"),
),
array(
"type" => "theme_fonts",
"heading" => __("Font Family", "mk_framework") ,
"param_name" => "font_family",
"value" => "",
"description" => __("You can choose a font for this shortcode, however using non-safe fonts can affect page load and performance.", "mk_framework")
) ,
array(
"type" => "hidden_input",
"param_name" => "font_type",
"value" => "",
"description" => __("", "mk_framework")
),
array(
"type" => "range",
"heading" => __("Font Size", "mk_framework"),
"param_name" => "item_text_size",
"value" => "16",
"min" => "10",
"max" => "100",
"step" => "1",
"unit" => 'px',
"description" => __("", "mk_framework")
),
array(
"type" => "dropdown",
"heading" => __("Font Weight", "mk_framework"),
"param_name" => "item_font_weight",
"value" => array(
__('Default', "mk_framework") => "inherit",
__('Light', "mk_framework") => "300",
__('Normal', "mk_framework") => "normal",
__('Bold', "mk_framework") => "bold",
__('Bolder', "mk_framework") => "bolder",
__('Extra Bold', "mk_framework") => "900",
),
"description" => __("", "mk_framework")
),
array(
"type" => "colorpicker",
"heading" => __("Font Color", "mk_framework"),
"param_name" => "item_color",
"value" => "",
"description" => __("", "mk_framework")
),
array(
"type" => "textfield",
"heading" => __("Extra class name", "mk_framework"),
"param_name" => "el_class",
"value" => "",
"description" => __("If you wish to style particular content element differently, then use this field to add a class name and then refer to it in Custom CSS Shortcode or Masterkey Custom CSS option.", "mk_framework")
)
)
));
And then you need the rest which I guess u know for mapping the shortcode and the attributes
I have the same options in my code as you:
vc_map( array(
"name" => __("Your Gallery", "my-text-domain"),
"base" => "your_gallery",
"as_parent" => array('only' => 'single_img'), // Use only|except attributes to limit child shortcodes (separate multiple values with comma)
"content_element" => true,
"show_settings_on_create" => false,
"is_container" => true,
"params" => array(
// add params same as with any other content element
array(
"type" => "textfield",
"heading" => __("Extra class name", "my-text-domain"),
"param_name" => "el_class",
"description" => __("If you wish to style particular content element differently, then use this field to add a class name and then refer to it in your css file.", "my-text-domain")
)
),
"js_view" => 'VcColumnView'
) );
vc_map( array(
"name" => __("Gallery Image", "my-text-domain"),
"base" => "single_img",
"content_element" => true,
"as_child" => array('only' => 'your_gallery'), // Use only|except attributes to limit parent (separate multiple values with comma)
"params" => array(
// add params same as with any other content element
array(
"type" => "textfield",
"heading" => __("Extra class name", "my-text-domain"),
"param_name" => "el_class",
"description" => __("If you wish to style particular content element differently, then use this field to add a class name and then refer to it in your css file.", "my-text-domain")
)
)
) );For anything else consider to hire someone or visit slack of Visual Composer
