I have map with 2 layers, one for supplier at the top and for country . the issue is when user selects land in the dashboard everythings got filtered as desired. I use calculation that supplier point are visible only in case a land or other fileds from other sheets get selected. In the Dashboard the suppliers for the selected country are hidden cause the Tableau selection highlighting.
you can see that if user select something on other sheet the daufalt map will get filtered and suppliers (blue icons) are visible.
my cocnlusion is the highlighting feature doesn't allow me to see the supplier points when map is clicked. on the particular map sheet everything is visible.
is there any option?

Your diagnosis is right, and your own clue nails the cause: selecting from another sheet filters the map (so suppliers stay full-opacity), but clicking the map selects a mark - and Tableau's default selection behaviour fades every non-selected mark to about 50%, which dims your whole supplier layer.
The clean fix is the 'dummy highlight action' trick, which neutralises that fade:
1. On the map sheet, make a calculated field - call it Highlight Fix - with the formula MIN(1) (a constant every mark shares).
2. Drop Highlight Fix onto the Detail shelf of the map.
3. Dashboard > Actions > Add Action > Highlight. Source and Target = the map sheet, run on Select, and set it to highlight on the Highlight Fix field only.
Because every mark shares the same constant, clicking one highlights all of them, so nothing greys out - your supplier points stay fully visible on click. Your existing filter action for the country selection keeps working untouched.
