Abstract In this paper, we study the notions of pointopen topology $C_p(X,H)$, openpoint topology $C_h(X,H)~[\text{resp.}~C_h(G,H)]$ and bipointopen topology
$C_{ph}(X,H)~[\text{resp.}$ $C_{ph}(G,H)]$ on $C(X,H)~[\text{resp.} C(G,H)]$, the set of all continuous functions from a topological space $X$ (topological group $G)$
to a topological group $H$. In this setting, we study the countability, separation axioms and metrizability. The equivalent conditions are given so that the space $C_h(G,H)$
is a zerodimensional topological group. Further, if $G$ is $H^{\star\star}$regular, then $C_h(G,H)$ is Hausdorff if and only if $G$ is discrete. It is shown that under certain
conditions the topological groups $C_p(X,H)$, $C_h(X,H)$ and $C_{ph}(X,H)$ are $\omega$narrow. Sufficient conditions are given for the topological spaces $C_p(X,H)$, $C_h(X,H)$ and $C_{ph}(X,H)$ to be discretely selective and to have a disjoint shrinking.
