unfocused widget fade on bingie layout -->
<include name="BingieUnfocusedWidgetFade">
<animation effect="fade" start="100" end="0" time="100" condition="!Control.HasFocus($PARAM[widgetid]) + !Control.HasFocus(1508)">Conditional</animation>
</include>
I Just hide the second faded row

But when I open the side menu all widgets disappeared

from looking at the image you posted it looks like you probably have turned off the Show all widgets option in the Homescreen layout
This option makes the content on the screen change depending on what item you select in the menu. So if the first item in the menu has no widgets set up, when you enter the menu all the widgets on the screen dissappear.

That's why it's nice to work with the hubs. This way you kind of make extra home screens with each 8 widgets available again.

In addon xml ((IncludesAnimations.xml))

start="100" end="0" time="100"

I changed end="0" it was end="50"

The widget becomes one row

But when i open the side menu all widget disappear

I could be wrong but I think the side panel is tied in as a group in the xml. That's why it has shifted as well. It's still there just moved off screen.
