I have an enumerate environment that I want to refer to later in my document using \ref and \label, but enumerate doesn't get numbered by section (the way, say, figure would). How can I add section numbers to enumerate?

I do not want individual, enumerated items to be numbered. Rather, I want the enumeration as a whole to be numbered.

What I am really looking for is something like this:

Algorithm 1.2

  • 1. Walk to store.
    2. Buy Milk
    3. Walk Home
  • ... /snip/ ...

    As described in Algorithm 1.2, it's easy to buy milk.

    I don't want to use a figure because I can't have it moving around the document. I don't want to use the theorem/definition/proof environments because of all the styling. The algorithm environments use a lot of styling too. I'm basically looking for a way to slap a title on my enumerate environment and give it a number that I can refer to.


    This is what I finally ended up with, based on Mico's post:

    \textbf{Algorithm \thealgcounter}

    Next time, please state your full requirements at the start. That'll save potential helpers some work. –  lockstep Feb 5 '12 at 15:39
    Can you elaborate why you don't want to use a theorem environment. I think what you are asking is a specific type of a theorem. It is relatively easy to change the style of theorem, for example, by using the ntheorem package. –  Aditya Feb 5 '12 at 15:44
    @Jake: Do you want to use the algorightm-environment. Please provide a minimal example. –  Marco Daniel Feb 5 '12 at 16:06

    If you're willing to load the amsmath package (you may be doing so already anyway...), you can just issue the command


    to have level-1 enumerations be subordinated to the section.

    Addendum. From your follow-up remarks, it would appear that you're not trying to change the appearance of LaTeX's own enumerate environment but, instead, want to create a custom environment that will be numbered within sections. (I.e., each time a \section command is encountered, numbering should start over at "1"; however, the section number needs to be prefixed to the environment number.) The following MWE illustrates how this may be achieved.

    \usepackage{amsmath} % needed for its \numberwithin command
    \newenvironment{myalg}{%      define a custom environment
       \bigskip\noindent%         create a vertical offset to previous material
       \refstepcounter{myalgctr}% increment the environment's counter
       \textsc{Algorithm \themyalgctr}% or \textbf, \textit, ...
       }{\par\bigskip}  %          create a vertical offset to following material
    \section{First section}
    Some text before the first algorithm environment \ldots
    Some thoughts\ldots \label{alg:first}
    More thoughts\ldots \label{alg:second}
    Some text after the second algorithm environment \ldots
    \section{Second section}
    Further thoughts\ldots \label{alg:third}
    \section{Third section}
    As we showed in algorithms \ref{alg:first}, \ref{alg:second}, 
    and \ref{alg:third}, \ldots

    Similarly to @Macro-Daniel's answer, I need numbering for the environment as a whole, not the individual items. –  Jake Feb 5 '12 at 15:37
    @Jake: I've provided an addendum to my answer. I now interpret your question as pertaining to a custom environment that is to be numbered within sections. –  Mico Feb 5 '12 at 18:30

    Based on the new informations of the comments I provide a new answer.

    To type an algorithm you can work the the package algorihtm. By using the command numberwithin (provided by amsmath) you can set the counter:

    \Require $x\ge5$
    \Ensure $x\le-5$
    \State $x\gets x-1$

    enter image description here

    To manipulate list environments like enumerate I really recommend the package enumitem. The package provides the key ref to manipulate the format of references.

    Here an example:

    \item \label{enum1} foo
    \item \label{enum2} bar
    \ref{enum1} and \ref{enum2}

    enter image description here

    Please consider to add a variant using label and resume, so I can delete my answer. –  lockstep Feb 5 '12 at 15:22
    This is close but not what I need...I edited my question to be a bit clearer –  Jake Feb 5 '12 at 15:33
