Welcome to the Question2Answer Q&A. There's also a demo if you just want to try it out.

Hi -

How do I customise the main Questions page (e.g. /question2answer/index.php?qa=questions) to show Answers immediately below the Question?

I've changed some code around, and it works okay if there is an Answer for the Question, otherwise it breaks ;-)

Here's how I managed to do it - using the Snow theme to override the q_list_item in qa-theme-base.

The code is a little long as it does a number of additional processing (cutting the text at end of words rather than at a fixed numerical point which would result in words being split, adding a "posted by" comment, allowing more of the comment to be made visible etc)

    public function q_list_item($q_item)
        $this->output('<div class="qa-q-list-item'.rtrim(' '.@$q_item['classes']).'" '.@$q_item['tags'].'>');

        //print_r($q_item); echo "***".$q_item['raw']['postid'];
        $answers = qa_post_get_question_answers($q_item['raw']['postid']);
        $rating = 0;
        $content = "";
        if (!empty($answers)) {
            $this->output("<script type='text/javascript'>
                    function toggleContents(elm) {
                        var titleContainer   = elm.parentNode.getElementsByTagName('div')[0];
                        var contentContainer = elm.parentNode.getElementsByTagName('div')[1];
                        titleContainer.style.display   = (titleContainer.style.display   == 'inline') ? 'none' : 'inline';
                        contentContainer.style.display = (contentContainer.style.display == 'inline' ) ? 'none' : 'inline';                      
            foreach ($answers as $answer) {
                if ($answer['upvotes'] >= $rating) {
                    $rating = $answer['upvotes'];
                    //$answercontent = $this->embed_replace($answer['content']);
                    $answercontent = $answer['content'];
                    // Determine the part of the content we will show
                    $offset = (strlen($answercontent) < 250 ? strlen($answercontent) : 250);
                    // Cut the content at a sensible point - end of a word
                    $pos = strpos($answercontent,' ', $offset);
                    if ($pos != False) $offset = $pos;

                    $content = substr($answercontent,0,$offset);
                    $remainingcontent = substr($answercontent,$offset);                    

            if ($remainingcontent!="") {
                $remainingcontent = '<div class="devqa-q-more" style="display:inline;" onclick="toggleContents(this)">... <a href="#!">(More)</a></div>
                             <div class="devqa-q-moreanswers">'.$remainingcontent.'</div>';
            } else {
                $remainingcontent = '';
            $this->output('<div class="devqa-q-answers">');
            if (isset($answer['handle'])) {
//                print_r($answer);
                // get user details (display avatar and name)
                $username = qa_db_read_all_assoc(qa_db_query_sub('SELECT handle FROM ^users WHERE userid = #',$answer['userid']), 'handle');
                $user = qa_db_select_with_pending( qa_db_user_account_selectspec($username, false) );
                //$revlink = isset($answer['title']) ? $answer['title'] : "Answer was edited";
                //$htmloutput = (isset($answer['updated']) ? date("Y-m-d H:m", strtotime($answer['updated'])) : "");
                $avatar = qa_get_user_avatar_html($user['flags'], $user['email'], $user['handle'], $user['avatarblobid'], $user['avatarwidth'], $user['avatarheight'], qa_opt('avatar_users_size'), false);
                $this->output('<span class="devqa-q-answers-respondent">');
                $this->output('<span class="qa-q-item-what">answered by </span>');
                $this->output('<a href="./index.php?qa=user&amp;qa_1='.$answer['handle'].'" class="qa-user-link url fn entry-title nickname"> '.$answer['handle'].' </a>');
                $this->output('<span class="qa-q-item-who-data">'.'('.$answer['points'].') points</span>');

        $this->output('</div> <!-- END qa-q-list-item -->', '');

How do we actually add this code... Can it simply be copied and pasted/appended to qa-theme-base? I ask because there are no line numbers. So, need to know how to affect the changes.
Yes, you can just copy it into the qa_theme file if you are using snow.

Some css changes may be needed too - just add these classes to the bottom o the qa-styles.css file:
.devqa-q-answers-respondent {
    display: inline;
    float: right;
    margin: -5px 10px;
    font-size: 11px;

.devqa-q-answers {
    padding-left: 10px;
    float: left;
    width: 520px;
    margin: 10px 0 10px;
    clear: none;
    overflow: hidden;
    color: #0179b5;
    display: inline;
    display: none;

Is there an update on this code. I just tried to deploy it and it broke the site. Disregard was able to find a work around with the mouseover located here: https://www.question2answer.org/qa/50582/show-question-content-on-the-main-page
