CGI Parameter hidesearch doesn't work anymore

we have upgraded Thruk version to [2.33-20191116]. Now the cgi parameter hidesearch doesn’t work anymore. The box is always closed although the hidesearch parameter is set to value 2.
Can anybody help ?

That “feature” has been removed. Since with the Thruk2 theme, the filter button overlaps with the status result table when open, it simply changes its colour to indicate an active search.
