Not all gamemodes are compatible with ULX Mapvotes. Reconstructed Ultimate Chimera Hunt and Extreme Football Throwdown are some examples. That's why I publish new versions of those gamemodes that are compatible with ULX Mapvotes and especially with this Mapvote Addon. Have a look at my workshop addons if you want.
If a gamemode that you want to play is not yet compatible with this addon please leave a comment. I'll then look into it.

Sadly I can't make this addon compatible with all other addons on the workshop and I won't try since it would be a lot of work.

If you believe that you found a bug leave a comment under this guide or on the addon's workshop page and I'll have a look

All of the following Options are accessible through the MapVotes GUI. You can open it up by typing !mvmenu in chat. Most stuff is self explanatory.

This Tab contains the gamemode prefixed for each gamemode. Most of them are already set by default through the gamemode file itself.
To entirely prevent a gamemode from appearing in MapVotes just put "nil" as a value.

This Tab contains the translated stuff that will be displayed during MapVotes. You can edit them to your liking

This tab allows you to restrict gamemodes from appearing in a MapVote depending on whether or not there's enough or too many players. This is useful since there's gamemodes that require more or less players than others.

In this Tab you can edit the gamemode descriptions that will be displayed during MapVotes.

This tab shows you how many many ratings and stars a Gamemode or Map has received. These will be displayed as stars during MapVotes.
You can edit those values by doubleclicking them.

This tab keeps track of how often a Gamemode or Map has been played.
You can, for whatever reason, edit those values by double clicking a line.

This Tab contains the Maps that are on Cooldown meaning they'll be excluded from MapVotes until a certain amount of other Maps have been played. This prevents players from picking the same map over and over again.

This tab shows you which maps contain CSS content. You can add more maps to this list or remove some.
These maps will be excluded from MapVotes if 'FilterCSSMaps' is set to true in the Config Tab.

This Tab controls the round or time limits of gamemodes. You can edit the values by doubleclicking them.

This Tab holds recommendations for additional addons to further optimize your server.

This Tab contains a list of all installed Addons on the server. There's a search function and you can click on in image to open up the Workshop page.

This Tab contains a list of all installed Maps on the server.

This Tab provides some useful Functions e.g. printing a list of all installed Addons to your or the server's console.

Over time data of maps and gamemodes that aren't installed on the server anymore can accumulate over time. To prevent your files from becoming too large this Tab can generate a list of all that useless data and allows you to delete them.

The more gamemodes your server has the longer it will take for players to join your server and download all necessary addons. To make life easier I made an addon which allows you to set up gamemode specific workshop collections to cut joining time to a fraction:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2965162101

Switch to the Gamemodes Tab and put a "nil" as the map prefix value. This will prevent the gamemode from appearing in MapVotes.

Open up the ULX menu by typing in !menu in chat and switch over to settings>ULX Player Votemap List. Then click on the map that you wanna blacklist and click on 'remove'. Done

Not all gamemodes have default map prefixes. In that case you can set them manually for this addon. Just switch to the Gamemodes Tab and double click the line you wanna edit. Type in the map prefixes separated by a comma for each prefix.

Switch to the Gamemodes Tab and put in the whole map name instead of a prefix.

(suggested by Vox Andrews)
Just create a text file with the gamemode's name in the data/mapvote folder. Call it ultimatechimerahunt.txt for example and type in the following lines:
sv_playermodel_selector_gamemodes 0
uch_roundtime 5
(Make sure to give each command a new line)
When the gamemode ultimatechimerahunt loads, the server automatically runs the console commands 'sv_playermodel_selector_gamemodes 0' to disable changing playermodels through the Playermodel Selector Addon and 'uch_roundtime 5' to set the round time to 5 minutes. This is just an example. You can type in whatever you want for whichever gamemode you want.

This will be reworked and added to the MapVote GUI.

There are two ways to use custom Map Previews instead of the default ones. The first and easy way is by using my Super Map Icon Maker.

The second way is as follows:
Take a screenshot of the map and edit it in an image editor like GIMP.
Make it 512x512 big and convert it to a .png. The name of it is important. Make sure it's the same name as the map!
For the map ttt_minecraft_b5 the corresponding preview would be called ttt_minecraft_b5.png.

After you're done create a folder with any name you like. Inside that create a file called addon.json and put this in it:
{
"title" : "YOURCUSTOMADDONNAME",
"type" : "ServerContent",
"tags" : ["fun","realism"],
"ignore" :
[
"*.psd",
"*.vcproj",
"*.svn*"
]
}
Think of a name for your new map icons addon and replace 'YOURCUSTOMADDONNAME'.

Then inside that folder create another folder called 'maps'. Inside that folder create a folder called 'thumbs' and put all your map preview files in it.
Now you can convert your addon folder to a .gma file and upload it to the workshop so everyone can have the same previews or you move your folder to your /addons/ folder so that they only apply for you.

By executing the console command mapvote_reportcssmap or clicking the corresponding button inside the GUI>ConCommands the server automatically adds the current map to the cssmaps.json file. If the config option FilterCSSMaps is set to true, this map won't appear in future mapvotes anymore
