SharePoint Content Query Web Part Title Field

Question

SharePoint 2013
I have a custom list on another site within SharePoint. How do I bring in all the columns? I see the title field on the Edit Web Part, but no matter how hard I try, I can't get multiple columns to show up.  Some of the Columns I am looking for from
the Custom List:
City
Vendor
Circuit ID
Thanks,
Chris

Amit,
Thanks for the links, but I am still missing something with the coding.  I am following the first link you gave me. 
These are the instructions from the page
In ContentQueryMain.xsl
Locate “ <xsl:template name=”OuterTemplate.CallItemTemplate”> “
Add:
<xsl:template name="OuterTemplate.CallItemTemplate">
<xsl:param name="CurPosition" />
<xsl:param name="LastRow" />
and add:
<xsl:when test="@Style='MyTask'">
<xsl:apply-templates select="." mode="itemstyle">
<xsl:with-param name="CurPos" select="$CurPosition" />
<xsl:with-param name="Last" select="$LastRow" />
</xsl:apply-templates>
</xsl:when>
Search:
<xsl:template name=”OuterTemplate.Body”>
And scroll down to add this line:
<xsl:call-template name="OuterTemplate.CallItemTemplate">
<xsl:with-param name="CurPosition" select="$CurPosition" />
<xsl:with-param name="LastRow" select="$LastRow"/>
</xsl:call-template>
What I don't know is where exactly to add the middle section in my xsl document.  Here is what I think I should have.  And the Circuit list below is another attempt at this too that has been unsuccessful.
<xsl:template name="OuterTemplate.CallItemTemplate">
<xsl:param name="CurPosition" />
<xsl:param name="LastRow" />
<xsl:value-of disable-output-escaping="yes" select="$BeginListItem" />
<xsl:choose>
<xsl:when test="@Style='NewsRollUpItem'">
<xsl:apply-templates select="." mode="itemstyle">
<xsl:with-param name="EditMode" select="$cbq_iseditmode" />
</xsl:apply-templates>
</xsl:when>
<xsl:when test="@Style='NewsBigItem'">
<xsl:apply-templates select="." mode="itemstyle">
<xsl:with-param name="CurPos" select="$CurPosition" />
</xsl:apply-templates>
</xsl:when>
<xsl:when test="@Style='NewsCategoryItem'">
<xsl:apply-templates select="." mode="itemstyle">
<xsl:with-param name="CurPos" select="$CurPosition" />
</xsl:apply-templates>
</xsl:when>
<xsl:when test="@Style='MyTask'">
<xsl:apply-templates select="." mode="itemstyle">
<xsl:with-param name="CurPos" select="$CurPosition" />
<xsl:with-param name="Last" select="$LastRow" />
</xsl:apply-templates>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="." mode="itemstyle">
</xsl:apply-templates>
<xsl:when test="@Style='CircuitList'">
<xsl:apply-templates select="." mode="itemstyle">
<xsl:with-param name="CurPos" select="$CurPosition" />
<xsl:with-param name="Last" select="$LastRow" />
<xsl:with-param name="StartNewGrp" select="$StartNewGroup" />
</xsl:apply-templates>
</xsl:when>
</xsl:otherwise>
</xsl:choose>
<xsl:value-of disable-output-escaping="yes" select="$EndListItem" />
</xsl:template>
I think I am getting close and your help is much appreciated.
