\footcite in Beamer

Question

I'm using biblatex and its \footcite command within beamer and when I want to reference two references together like \footcite{ref1,ref2}, I get a single number with two contiguous references as footnote?

my biblatex code is as follows and i am not sure waht is wrong:

\usepackage[style=verbose,autocite=footnote,maxnames=10,babel=hyphen,hyperref=true,abbreviate=false,backend=biber]{biblatex}       

Answer 1

I want to refer the documentation of biblatex:

\footcite[ prenote ][ postnote ]{ key }

\footcitetext[ prenote ][ postnote ]{ key }

These command use a format similar to \cite but put the entire citation in a footnote and add a period at the end. In the footnote, they automatically capitalize the name prefix of the first name if the useprefix option is enabled, provided that there is a name prefix and the citation style prints any name at all. \footcitetext differs from \footcite in that it uses \footnotetext instead of \footnote.

You can see that this behavior is independently from beamer.

\listfiles
\documentclass{article}
\usepackage[style=verbose,autocite=footnote,maxnames=10,babel=hyphen,hyperref=true,abbreviate=false,backend=biber,mcite]{biblatex}
\addbibresource{biblatex-examples.bib}
\begin{document}
Test\footcite{ctan,companion}

Test\footcites{ctan}{companion}

Test\mfootcite{ctan,companion}

Test\footcite{ctan}\footcite{companion}
\end{document}

You can create you own command. My first idea is very simple:

\newrobustcmd*\footcitesep[1]{%
   \forcsvlist{\footcite}{#1}%
}
