ZSH tab completion - don't fill in first file

Question

If I have files "something1" and "something2" in a folder, how do I make ZSH's tab completion fill in only the common characters? For example, I would type:

som<Tab>

and I want it to fill in with "something", not "something1".

Current zstyles:

zstyle ':completion:*' special-dirs true
zstyle ':completion::complete:*' use-cache on
zstyle ':completion::complete:*' cache-path ~/.zsh/cache/$HOST
zstyle ':completion:*' list-colors ${(s.:.)LS_COLORS}
zstyle ':completion:*' list-prompt '%SAt %p: Hit TAB for more, or the character to insert%s'
zstyle ':completion:*' menu select=1 _complete _ignored _approximate
zstyle -e ':completion:*:approximate:*' max-errors \
zstyle ':completion:*' select-prompt '%SScrolling active: current selection at %p%s'
zstyle ':completion:*::::' completer _expand _complete _ignored _approximate
zstyle -e ':completion:*:approximate:*' max-errors \
zstyle ':completion:*:expand:*' tag-order all-expansions
zstyle ':completion:*' verbose yes 
zstyle ':completion:*:descriptions' format '%B%d%b'
zstyle ':completion:*:messages' format '%d'
zstyle ':completion:*:warnings' format 'No matches for: %d' 
zstyle ':completion:*:corrections' format '%B%d (errors: %e)%b'
zstyle ':completion:*' group-name ''
zstyle ':completion:*' matcher-list 'm:{a-z}={A-Z}'
zstyle ':completion:*:*:-subscript-:*' tag-order indexes parameters
# zstyle ':completion:*:processes' command 'ps -au$USER'
zstyle ':completion:*:*:kill:*:processes' list-colors '=(#b) #([0-9]#)*=0=01;31'
#zstyle ':completion:*:processes' command 'ps ax -o pid,s,nice,stime,args | sed "/ps/d"'
zstyle ':completion:*:*:kill:*:processes' command 'ps --forest -A -o pid,user,cmd'
zstyle ':completion:*:processes-names' command 'ps axho command' 
#zstyle ':completion:*:urls' local 'www' '/var/www/htdocs' 'public_html'
zstyle ':completion:*' hosts $(awk '/^[^#]/ {print $2 $3" "$4" "$5}' /etc/hosts | grep -v ip6- && grep "^#%" /etc/hosts | awk -F% '{print $2}') 
zstyle ':completion:*:*:(^rm):*:*files' ignored-patterns '*?.o' '*?.c~' \
zstyle ':completion:*:functions' ignored-patterns '_*'
zstyle ':completion:*:*:*:users' ignored-patterns \
zstyle ':completion:*:scp:*' tag-order \

zstyle '*' single-ignored show

Answer 1

Adding this to ~/.zshrc works for me:

setopt noautomenu
setopt nomenucomplete

Answer 2

remove line:

setopt menu_completion

from your .zshrc

and it should work fine with filling unambiguous part first.
