Html Nanogallery2-带空格的标记

我希望有带有空格的标签，但我似乎无法这样做。画廊工作正常，标签部分工作，但我无法进入他们的空间。我的代码如下所示（我也尝试过使用标题中带有#的标记）

有没有办法在标签中添加空格？任何帮助都将不胜感激

<div id="nanogallery2"
// gallery configuration
data-nanogallery2 = '{ 
"thumbnailWidth":   "auto",
"thumbnailHeight":  200,
"itemsBaseURL":     "https://nanogallery2.nanostudio.org/samples/",
"thumbnailLabel":     { "display": "false" },
"galleryFilterTags": true,
"galleryFilterTagsMode": "multiple",
"thumbnailHoverEffect2": "imageScaleIn80",
"allowHTMLinData": "true"
}'

<!-- content of the gallery -->
<a href="berlin1.jpg" data-ngtags="first way" data-ngthumb="berlin1t.jpg">Berlin 1 #first</a>
<a href="berlin2.jpg" data-ngtags="second way" data-ngthumb="berlin2t.jpg">Berlin 2 #Second</a>
<a href="berlin3.jpg" data-ngtags="third way" data-ngthumb="berlin3t.jpg">Berlin 3 #Third</a>
